title: [Contribution of the CO2 laser in the sterilization of various infections of dental origin].
abstract: The CO2 laser (lambda congruent to 10.6 micrometers) induces structural changes in the mineralised tissues of the dental organ: fusion, recristallization, increase in hardness and sterilisation. (Report at the Academie des Sciences, December 1980). Thanks to Professor C. Freche, 200 cases have been treated using the FLF 25 since June 1980: 1) apical infections: 40 cases. The laser closes the lumen of the canaliculi, hardens and sterilises the dentine; 2) dentino-pulp infections: 150 cases. The laser volatilizes the area of caries in live teeth, hardens and sterilises the dentine. With exposed pulp (6 cases) the laser coagulates, sterilises and permits closure; 3) periradicular infections: 10 cases. The laser cleans, sterilises and hardens. Parodontal pockets are cleansed; 4) mucosal or gingival surgery is bloodless, atraumatic and particularly facilitated. The laser has become an instrument for the prevention of the complications of dental disease.
